Abstract

A pyroelectric ceramic material based on Pb(Sn1/2Sb1/2)O3 modified PZT system is studied as a function of the amount of Pb(Sn1/2Sb1/2)O3 and PbTiO3. With increasing the Pb(Sn1/2Sb1/2)O3 amount the dielectric constant increases up to 10mol% and then decreases, but the pyroelectric coefficient decreases and as the PbTiO3 contents increase in the 10mol% added PZT system, the dielectric constant increases but the infrared sensitivity decreases. The good pyroelectric material has low dielectric constant and no pyrochlore phase, but does not depend in the amount of remanent dipole, and its composition sites around ferroelectric-to-antiferroelectric phase boundary.
